Does environmentalism cause amnesia?

But what about the supposedly warming climate? According to the EPA, “average temperatures have risen more quickly since the late 1970s,” with the contiguous 48 states warming “faster than the global rate.” Yet U.S. food production over the same time has also risen by robust percentages even as the number of acres under cultivation has been steadily falling for decades.

In other words, even if you believe the temperature records, a warming climate seems to correlate positively with greater food production. This has mainly to do with better farming practices and the widespread introduction of genetically modified (GMO) crops, and perhaps also the stimulative effects that carbon dioxide has on photosynthesis (though this is debated). Warming also could mean that northern latitudes now not suited for farming might become so in the future.

But whatever the reason, the world isn’t likely to be getting any hungrier. Quite the opposite: Purely natural (as opposed to man-made) famines are becoming unknown.
